This is an interesting topic I think. I have Asperger's Syndrome and I would consider myself to be an introvert. I'm quite shy but I believe that I'm more of a confident person now than when I was in my mid-teens and I'm currently 23. I feel uncomfortable in certain kinds of places such as certain bars and pubs. I have never been to a nightclub and I never want to. I know quite a few people and I have a fair few Facebook friends. I get on with all of them as far as I'm aware but I wouldn't consider them all to be true friends of mine. I would consider most of them to be more like acquaintances to me. I would, however, be happy to have chat with any of them and I try to make sure that I post at least a birthday message to all of my Facebook friends on their walls when their birthday comes around. I do, though, have a few proper friends who I see every now and then. At the moment, I feel content with the situation I'm in. I'm not a very outgoing person but this might have something to do with me being rather reserved as a person and my disability.
I think it's difficult to define what a poor social life is. People are different and not everyone is an extrovert who likes going to big parties every weekend. I think it's up to you what you want for yourself personally. blueclay, if you're happy yourself with your current social life, then I don't see why you should change anything. However, if you're unhappy with it, then you should try to do something about it. These are just my personal opinions and you can ignore them if you want to. As for your theory about women being turned off by men who don't appear to have a great social life, I can't really comment on that as I don't know if that is the case with most women. I'm not the most confident man when it comes to talking to girls but one of my friends is a girl, so I guess that's good.
I tend to agree with you, but I'm one of those people who have a hard time to recognize they would really love to have a more interesting social life and specially meet more women ( I have had couple of gf on the past) but thats has been too few and far in between to fulfill my desires.
